Agile and Compact ZW50 and ZW80 Wheel Loaders

Agile footwork and high power. Those come

from the Hitachi compact wheel loaders,

ZW50 and ZW80. The dynamic styling is

impressive, refl ecting high mobility, power and

productivity.

Note:Photos and illustrations shown on this brochure may include optional equipment.The machines shown are positioned for the sake of demonstration. When leaving the machine at job sites, please take necessary safety measures: for instance, rest the front attachment on the ground.

Universal Quick Coupler Switch attachments from the

comfort of your cab. Enables

the rapid and seamless

replacement of working tools.

Electric Controlled Parking Brake The electric controlled parking brake functions prevent dragging as well as seizure. If the engine stops, the parking brake is applied automatically.

Locking Front Differential(ZW80) Manually locking front differential axle is standard.

Easy-to-Read Monitor

The easy-to-read monitor allows the operator to check operating conditions of the machine at a glance. Meters and indicators are grouped for easy monitoring.

Features of HSTContinuously adjustable speed can beachieved by operating the accelerationpedal - enabling start, acceleration, andstopping to be performed automatically. • Operation is made easy with smooth automated

speed controls • Precision operations possible at extremely low

speeds • Excellent mechanical operations with highly

responsive acceleration • Smooth startup on slopes using HST brake • Excellent traction at all speeds range

Ergonomic Control Lever

The control lever is ergonomically

designed for easy, speedy control of the

front attachment.

Panoramic CabThe panoramic cab gives almost all-round visibility with the wide front glass window and pillarless rear corners.

Low-noise Level in cab The cab is sound insulated with highly sealing design, new low-noise engine, and rubber-mounted operator frame and hydraulics.

Boosted Operator Comfort and Safety

Adjustable Suspension

The short-stroke suspension seat is provided as standard equipment to absorb shocks and vibration during operation, reducing operator’s fatigue in long hours of operation.

Walkthrough Type Cab

The walkthrough type cab allows for easy access from either side. The fl at fl oor enables easy cleaning.

A long-stroke suspension seat, which well absorbs shocks and vibration, is standard.

ROPS/FOPS* Cab

The ROPS/FOPS cab is adopted to protect the operator from roll-over accidents and falling objects.

ROPS: Roll-Over Protective Structure: ISO3471 FOPS: Falling Object Protective Structure: ISO3449

Neutral Engine Start System

If the forward/reverse lever is not in neutral (N), the engine cannot start, enhancing safe operation.

Reducing Environmental ImpactResin parts are marked for identifi cation, facilitating recycling after disposal.

Easy Access to Operator’s StationThere are handrails and large steps

mounted on both the left and right of the

operator’s station for easy access.

Control Lever Lock The control lever and auxiliary function lever are lockable for safety.

Lockable Filler Cap and Engine Cover

The fi ller cap and engine cover can be locked with the engine key for protection against pilfer proof.

HN Bushings

The time-tested HN bushings are utilized at joints of the front attachment, extending lubricating intervals up to 250 hours.

Note: For an initial 50-hour lubricating interval, refer to the Operator's Manual.

Concentrated Servicing Points

Wide-Open Engine Cover Daily maintenance is simplifi ed with the wide-open engine cover and low-profi le counterweight. The engine cover can be opened at a touch and held with a gas damper for quick inspection, replacement and replenishment.

Aluminum Radiator and Oil Cooler

The aluminum radiator and oil cooler are located side by side for easy cleaning.

Easy Remote Lubrication

Remote lubrication and engine oil drain eliminates the need for getting under the rear oscillation.

Concentrated Electric Parts Electric parts, such as relays, are grouped at one point for simple maintenance.

Coolant Reservoir The coolant reservoir allows for direct coolant level checking.

Double-Element Air CleanerThe double-element air cleaner is located strategically for the convenience of inspection and replacement.

Fuel Filter and Water SeparatorA cartridge type fuel fi lter is used for easy replacement. The water separator has a transparent cup for easy water level checking.

Brake Oil Reservoir The brake oil reservoir allows direct checking of brake oil. Its warning light turns on for alerting.

Battery Battery electrolyte level can be checked at a glance through an opening of the counterweight.
